Last revised: 09/10/2008
Source: US-CERT/NIST

Overview

Bugzilla 2.20rc1 through 2.20 and 2.21.1, when using RSS 1.0, allows remote attackers to conduct cross-site scripting (XSS) attacks via a title element with HTML encoded sequences such as ">", which are automatically decoded by some RSS readers. NOTE: this issue is not in Bugzilla itself, but rather due to design or documentation inconsistencies within RSS, or implementation vulnerabilities in RSS readers. While this issue normally would not be included in CVE, it is being identified since the Bugzilla developers have addressed it.
